FALL-ROPE CARRIER Specification of Letters Patent.

Patented June 9, 1908.

Application led July 9, 1907. Serial No. 382,920.

To all whom it may concern.'

Be it known that I, Asi-IER LAMBERT, a citizen of the United States, and a resident of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Fall Rope Carriers, of which the following is a specification.

This invention relates to conveyers or cable ways for hoisting and conveying.

The object of this invention is to provide a rope carrier which is simpler, more certain in operation, and less liable to derangement than any heretofore known or used.

In conveyers of this character it is desirable and necessary to support the flexible ropes employed from the main cable or track way so as to prevent sagging and interruption to the successful movement of the carrier, and so as to permit the raising and lowering of the loa'd or bucket, whether full orempty, at any point between the terminal stations. Each of a series of carriers should be automatically movable at a predetermined and characteristic rate so as to maintainthe proper space or distance between successive carriers. each carrier is provided with a propelling device or element including a grooved wheel, sheave or pulley; this propelling device engages the under side of the main track or cable and the upper side of the endless haul rope g the track, the propelling device and the haul rope are in one and the same vertical plane, and the effort of the haul rope has a tendency to force the propelling device into engagement with the main track this steadies the carriers and prevents wabbling. I provide for forcing the haul rope into engagement with the propelling device by means additional to this effort of the haul rope. This means consists in the employment of an adjustable spring and suitable connecting device arranged to maintain a continuous pressure.

My improvement herein described and particularly claimed consists of a three-quarter speed rope carrier, that is, a rope carrier which moves at three-quarter the speed of the load carriage. Other ro ecarriers should be provided to travel at onealf speed and at one-quarter speed.

I provide a track rope of large diameter and a haul rope of small diameter; lthe propelling device of the rope carrier consists of a wheel having two flanges, the central contact face of this wheel is of smaller diameter;

To attain this objectV the haul rope engages this contact face, the contact face of larger diameter formed by the two flanges engages the main track. To maintain the haul rope in working engagement with the y smaller diameter contact face, I provide a grooved wheel or sheave supported in a separate frame. This frame is located between said frame plates and also between the flanges of the propelling wheel. The frame is adjustably connected with the main frame so that a spring in position between the frames operates to draw the frames in a fixed direction and causes the grooved wheel to exert a pressure upon the under side of the haul rope forcing it into engagement with the smaller contact face of the propelling Wheel while the largerl contact face of said. wheel is also pressed against the under side of the track way. A narrow exterior rim or frame forms a support for the adjusting device.

The accompanying drawings illustrate my invention:

Figure 1 is a side elevation partly in section Fig. 2 is an elevation partly in section, and Fig. 3 is a bottom view of the under side of the propelling device.

Thetrack rope is shown at 12, the haul rope at 14, the hoist rope at 16 is supported on a sheave 20 in the frame 19. These ropes all pass between the cheek plates of the frame 19 which plates are suitably bolted together and spaced a fixed distance. Wheels or sheaves 21 fixed in the frame 19 travel on the'track 12 5 the propelling device CZ engages the under side of the track 12, the propelling device d consists of two flanges 50 and 51 having an arc-shaped contact surface a second grooved. contact surface e is of shorter radius and engages the upper side of the haul rope 14. The grooved wheel 22 is designed to under-run the haul rope 14 and press it to engagement with the contact surface e of the propelling device d. The wheel -22 is supported on axle 69 in a triangular frame having a base piece g and side pieces 7L which are hinged to the base piece g by bolts 70. These side pieces are connected to an adjusting device by the bolt 71 this adjusting device consists of two links, t and u, hinged together at 34. The link u is hinged on the support 71 and the link t is hinged on the support 72. The threaded bolt g is connected to the bolt 34, bolt g passes through the plate p fixed to the frame f. There is a spring s on bolt q located between the plate p and the ring r on the bolt. The pressure of the spring s is reg ulated by the nut m and the set nut n. This spring and the links t and u, arranged as described, act to press the base piece g containing the wheel 22 toward the contact face e of the propelling device d, and also presses the contact face 50, 51, into engagement with the under side of the track 12 and the track 12 into engagement with the wheels 21.

In a co-pending application, Serial No. 382918, filed July 9, 1907, l have shown, described and claimed the invention, a specific modification of which is herein shown and described.

In a co-pending application, Serial No. 382919, filed July 9, 1907, I have shown and described the invention, a specific modification of which is herein shown and described.

What I claim and desire to secure by Letters Patent is:

1. In a conveyer the combination with the track of -a rope carrier having a frame or support, a propelling wheel in said frame, said Wheel having two contact faces at respectively (fliflerent radial distances and means for pressing the track into engagement with the face of longer radius and the haul rope into engagement with the face of shorter radius, said means consistingv of a grooved wheel, a frame or support therefor, and a spring tending to draw said frames in a predetermined direction.

2. In a conveyer the cpmbination with the track of a rope carrier having a frame or support consisting of two parallel plates bolted together, a propelling wheel in said frame, said wheel having two contact faces at respectively different radial distances, and means for pressing the track into engagement with the face of longer radius andthe haul rope into engagement with the face of shorter radius, said means consisting of a grooved wheel, a separate frame therefor located between the plates of the first named frame, an adjusting device connecting said frames and an adjustable spring for controlling said device.

3. ln a conveyer the combination with the track of a rope carrier having a frame or support, a 'propelling wheel in said frame having t'wo flanges forming a contact face for the track, a grooved contact face between said flanges of shorter radius, a grooved wheel located between said `flanges a frame to sup-I port the last named wheel, and means for adjustably connecting said frames.

4. In a conveyer the combination with the track of a rope carrier having a frame or support consisting of two parallel plates bolted together, a propelling wheel in said frame, said wheel having two contact faces at respectively different radial distances, and means for pressing the track into engagement with the face of longer radius and the haul rope into engagement with the face of shorter radius, said means consisting of a grooved wheel, a separate frame therefor located between the plates of the first named frame, an adjusting device connecting said frames, and a separate exterior support for said adjusting device.

ln testimony whereof, l have signed my name to this specification, in the presence of two subscribing witnesses.

ASHER LAMBERT.
